We at MMB have been very busy recently, and are now proud to present our new complete kit, the Sub-Sonic, a 620mm long fast electric dynamic diving submarine.

The kit includes everything you need except a prop, motor (400/540 brushed or brushless), batteries, speed controller and radio.

We displayed the sub at Wicksteed this weekend and caused quite a stir with it.

The kit, including hull, WTC tube, end caps, propshafts, motor mount, all dive planes and screws plus much more retails for just £90. Colours are red, orange, yellow, blue, white, grey and black. The sub also comes with fully detailed instructions taking you through every step of the build, plus a CD with photos of every part. It is suitable for beginner and expert alike.
